On my 2012 t100 I am taking the entire rear fender off and putting a custom tail light on. No turn signals how do I reuse the factory harness for a two wire self grounding tail light. Thanks
Unfortunately I tossed a lot of my notes from the project but this should help. I removed everything in pink and then some more. I don't see why you couldn't ground to the frame or the fender. Let us know what you end up doing.
Prime riding season here in Michigan...so forum surfing for me is at an all time low.
Blue wire in the harness attaches to the brake light. Red wire attaches to the running light. Your self grounding fixture will need a ground run from the housing to the frame...unless, of course, you are fitting an alloy mudguard. Hard to get a ground through that plastic fender.
